中調整彈出式下拉對話框的大小我想創建一個帶有複選框的多選微調框,但我不知道如何這樣做,所以我想出了一個替代下拉列表multislect popupdialog。我能夠顯示彈出式窗口,但是我的問題是......正如您在圖片中看到的那樣,彈出窗口不會在信息類型框中對齊......您能幫助我嗎?如何在android
這裏是我在popupInformationType.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/PopUpViewInformationType"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:orientation="vertical">
<ListView
android:id="@+DropDownList/dropDownListInfoType"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#d3d3d3"
android:cacheColorHint="@color/cachecolorhint"
android:divider="#000"
android:dividerHeight="0.5dp" >
</ListView>
</LinearLayout>
代碼,這裏是我的dro_down_list_infotype.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
<CheckBox
android:id="@+DropDownList/checkboxInfoType"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@drawable/selector_checkbox"
android:layout_marginLeft="10dp" />
<TextView
android:id="@+DropDownList/SelectOptionInfoType"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000"
android:layout_gravity="center_vertical"/>
</LinearLayout>
代碼,這裏是我的代碼中的一部分調用彈出窗口的MainActivity
private void initiatePopUpInfoType(ArrayList<String> informationTypes, TextView tv_InformationType){
LayoutInflater inflater = (LayoutInflater)IreportMain.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//get the pop-up window i.e. drop-down layout
LinearLayout layoutInfoType = (LinearLayout)inflater.inflate(R.layout.popup_informationtype, (ViewGroup)findViewById(R.id.PopUpViewInformationType));
//get the view to which drop-down layout is to be anchored
RelativeLayout layout2 = (RelativeLayout)findViewById(R.id.relativeLayout2);
pwInfoType = new PopupWindow(layoutInfoType, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
pwInfoType.setBackgroundDrawable(new BitmapDrawable());
pwInfoType.setTouchable(true);
//let pop-up be informed about touch events outside its window. This should be done before setting the content of pop-up
pwInfoType.setOutsideTouchable(true);
pwInfoType.setHeight(LayoutParams.WRAP_CONTENT);
//dismiss the pop-up i.e. drop-down when touched anywhere outside the pop-up
pwInfoType.setTouchInterceptor(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
pwInfoType.dismiss();
return true;
}
return false;
}
});
//provide the source layout for drop-down
pwInfoType.setContentView(layoutInfoType);
//anchor the drop-down to bottom-left corner of 'layout2'
pwInfoType.showAsDropDown(layout2);
//populate the drop-down list
final ListView listInfoType = (ListView) layoutInfoType.findViewById(R.DropDownList.dropDownListInfoType);
InfoTypeListAdapter adapter = new InfoTypeListAdapter(this, informationTypes, tv_InformationType);
listInfoType.setAdapter(adapter);
}
ü也可以嘗試用pwInfoType.setWidth(tv_InformationType.getWidth()); –
